COMMENTS: Reviewed by O'Farrell and Blaustein (1974a, Mammalian Species, 46). The suggestion by Hall (1941:380-382) of hybridization between megacephalus and pallidus was discounted by Hafner et al. (1979). Also, Hall's suggestion (1981:560) that leucotis may warrant specific status is not supported (see Hafner and Hafner, 1983).
